I once saw a link on a PR 8 page by Doc Searls do absolutely nothing to rankings for the target site. It did, however, bring in a lot of direct traffic. It was experiences like this that taught me to dig a lot deeper into Google's ranking algorithm.
However, you may yet see a boost. Make sure your page clearly offers exactly what the link says it will - and those are the search terms that might pop for you. Sometimes the positive effect of a link does a slow fade-in.
